GAS-RANGE.

To allwhom it may concern:

Be it known that we, ABRAM G. Mor'r,

Junior, and ALBERT J. MEYER, citizens of the United States, and residents of Philadelphia, county of Philadelphia, State of Pennsylvania, have invented certain Imrovements in Gas-Ranges, of which the ollowing is a specification.

One object ofour invention is to construct an oven section, including an oven and a broiler compartment, so as to dispense with the heavy cast iron braces usu- 3 ally employed and to utilize the shaped sheet iron asa brace.

A further object of the invention is to im prove other details in :the construction of the oven, whereby a very substantial structure ismade at a comparatively low cost.

In the accompanying drawings:

Figure 1 is a front view in elevation of the oven and broiler sections ofa gas range, the base section of the range being omitted,

as it forms no part of our invention;

1 is the oven section. 2 is the broiler sec-1 tion of the overhead portion of a gtts range in the present instance. This portion is usually supported on brackets a sufiicient distance above the main body of the gas range, or the combined gas and coal range, so as nottointerfereswith the cooking utensils on-the main orange; :3 is the bottom p ate having a Specification of Letters.

rolled rim 4. at its outer end. This bottom plate extends the full width of the range and the full depth of the oven portion.

Patented se t. 13, 1921.

By making the bottom plate 3 of sheet metal;

structure, as the iron is stiff enough to Sup-w port the bottom plate properly and the structure carried thereby.

6 is the top plate of the structure having a rolled rim.7 with turned up edge 8.

This rim acts as a support and stiffens the top plate. The two rrims also. give an ornamental rounded appearance to the structure, as clearlvshown in Fig. 1.

9 is one of the side plates having a rolled site sideplate having a rolled rim'13. In

the present instance, the top plate 6 and the side plates 9 and 10 are made in one piece and the-rim is cut at w, in the form of a V and the plate is bent at right angles,

. edge, which is shaped at top and bottom to l fit the rims 7 and 4. Plates 17 and 18 cover the joints.

19, 19 are cover-plates for the jointsibetween the side plates and the bottom plates. By forming the side the top and providing t e heavy rolled rim, weare enabled to stifienthestructure, while using comparatively light material.

20is the back plate, which is preferably lates integral with g flan ed at top and bottom and may be spot??- wel ed to the top and bottom lates or riveted thereto, as desired. It wil be noticed that the broiler section is not so deep as the oven section and is separated by a partition 21 from a compartment 22 through 1 which passes the flue 23 for theproducts of combustion of the coal of the range, when a coal sectionis used. 1 Connecting the flue 23 with the upper portion of the oven l is a fine, or duct,24 to can? the odors from them oven to the main flue. the upper ortion fiofthe oven is a duct 25 extendingt e full depth of the oven and terminating at the forward end thereof and open at the forward end so that any gases, or fumes, in the 6, having transverse portions 28, 28.

oven vvill pass to the forward portion of the oven and then throughthe duct 25 to the fine 24;. At the back of the oven is an inner oven plate 26 forming an air chamber be 32,1 which extend back of the rolled rims 13 and: 16. These are the vertical stiffening :members of the structure and also are the supports for the, hinge projections 33 and the keeper projections 34. .These projections are cylindrical and pass through correspondingly eylindricalholes in the rim, making a neatfinish.

35 is a plate located-at. the broiler section and havingaportion 36 extending over the upper portion of the broiler section and having an opening 37 for the burner 38. 39

is an extension,:which is back of therolled rim 9 and has hinge projections 40 which extend through openings in the rim. 41 is'the door of the broiler-section and 42 is the door. of the oven section. The portion 38 of the burner, which is located above" the broiler section,. is shaped, :in the present instance, as shown in Fi 2, andis-support 1 ed at .the rearb -brac ets 43 and by the front plate 36, Whiletheburner tube 30 is located under the bottom. plate 14 of the ovenseetion' and is supported by the front plate 28 and by a socket on the back plate.

The supply "pipe 45 extends back of the lower rim 4 and is coupled to the burner- 30 of the oven and is connected'by a vertical .pipe 46 vvith'the burner 38 of the broiler. xThe oven bottom p1ate-44 is supported on angle bars 47, preferably of cast metal.

"These barshave'lugs which rest upon lugs on the plates 31-and are secured'to said plates 45' by' bolts48. In the oven are angle slideays 49'made of'cast metal and of the shape when they areinov'ed out. In the bottom plate 3 is aslot 3 shown in Fig-1 0. There are lugs onthe plate 31 secured thereto by bolts 8 Cast integral with these bars is a projection 50, which prevents the tipping of the oven slides substantially the'full depth of the burner 30; slot admits'air to the chamber in which the :burner is located. The bottonr plate: is cut andthe portions'bent. upso as *--'to formfa tapered nozzle, as shown, and

' thisconstruction also stiffens the bottom plate 3. i

It w

ill be noticed that the bottom plate Moi? the oven'is "discontinued at each side 3:30 as to form passages 51' for the products o combustion, as it will be understood that the 5 gas burner 30 is located below the solid 'oven'p'l ate Fig. 5, and the products extending j The plate at the side of the oven structure is spaced :1 distance from the end plate 9 of the oven and spacing lugs 56 are formed on the slide supporting plate so as to hold it in proper relation to the door opening. The other plate has a portion which makes a finish at the open side of the broiler structure.

In the bottom of the broiler structure is a series of openings 57, which admit air to the broiler section and the rear partition of the broiler stops short of the top plate 6 forming a passage 58 so that the gases may escape into the fine chamber 22 and to the flue 21.

By the above construction, it will be seen that the only cast metal parts used in this portion of the gas range are two frames for the front of the structure on which the doors are hung and the slideways. The bracing is accomplished by the heavy rolled rims of the sheet metal plates.
